*	feat: Add initial Supervisor Mode Trap Handler	Richard Qin	2025-12-10	3	-16/+240
\| \| \| \| \| \| \| \| \| \|	Implement the initial mechanism for handling traps and exceptions in Supervisor Mode. Set up the stvec Control and Status Register (CSR) to direct all S-Mode Traps (Interrupts and Exceptions) to a unified assembly entry point. Implemented assembly code for saving and restoring the Trap Context (register state). Provides the foundational framework necessary for future Timer Interrupts and System Calls.
*	feat: Initial PMM implementation	Richard Qin	2025-12-09	3	-3/+224
\| \| \| \| \| \|	Introduce the foundational Physical Memory Manager (PMM) and restructure the project for modularity. Implemented basic PMM and related memory management headers (mm/pmm.h, mm/vm.h). Updated Makefile and build process to support new modular structure.
